唤醒手机屏幕并开锁

这个我是使用在讯飞语音的语音唤醒里面的:

//锁屏、唤醒相关
private KeyguardManager km;
private KeyguardManager.KeyguardLock kl;
private PowerManager pm;
private PowerManager.WakeLock wl;

private void wakeAndUnlock(boolean b) {
if(b) {
//获取电源管理器对象
pm=(PowerManager) getSystemService(Context.POWER_SERVICE);
//获取PowerManager.WakeLock对象，后面的参数|表示同时传入两个值，最后的是调试用的Tag
wl = pm.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.SCREEN_BRIGHT_WAKE_LOCK, "bright");

//点亮屏幕
wl.acquire();

//得到键盘锁管理器对象
km= (KeyguardManager)getSystemService(Context.KEYGUARD_SERVICE);
kl = km.newKeyguardLock("unLock");

//解锁
if (km.inKeyguardRestrictedInputMode()) {
// 解锁键盘
kl.disableKeyguard();
}
} else {
//锁屏
kl.reenableKeyguard();

//释放wakeLock，关灯
wl.release();
}

}

还有两条权限:

<uses-permission android:name="android.permission.WAKE_LOCK" />

< uses-permission android:name="android.permission.DISABLE_KEYGUARD" />
